The beek 7 en@ nei/ere 8 me mace in one integral piece, preferably leather, a construction materially saving cost and presentingl a neat appearance. l. have found pigskin the best material for the back and covers. The use of paste for securing together several layers of the covers is dief pensedwithand 'this Iobviates the object1onable feature of buckling or bending caused by the drying of the paste or differences in shrinkage of the layers under varying conditions ot temperature and moisture. rlhe channels or grooves 9 adjacent to and parallelwith the operating parts weaken the material of the covers so as to form a sort of binge. By removing the material to form thechannels or grooves-@the covers are perfmitted to close neatly and snugly as best infbination a back and covers composed ot a single-plyintegral piece of iexible materia-l, a l0ose-leat` binding mechanism, and

means passin through said'baolrand fastening said mec anism inner face thereof.

2. A temporary binder including in compermanently upon the b ination aback and. covers composed of a-v single-ply integral piece of leather' so that.

the cnt edges of said piece ot leather constitute the edges of the covers and back, a loose-leail binding mechanism, and means passing lthrough said back and fastening Said mechanislrn permanently upon the inner face thereof.

8. A temporary binder including iu combinati'on a 'backand covers composed of a ing` said back singleply integral piece ot liexible material7 a loosenea2 binding' mechanism on the inner side 'of said back, a binding plate on the outer side or" said back and means Jfor clampbetween'said mechanism and said plate.

e. A. temporarybinder inbluding in comf bination a buck and covers composed of a single-ply integral piece of flexible material, a. loose-.leat binding mechanism .on the inincassa ner side of said back and a binding plate on the outer side of said back having ears passing through Asaid back and engaging a part oit' said mechanism so as to fasten the latter` to said back.

5. A temporary binder including in combination a back and' covers composed of a single-ply integral piece of liexible material, and a loose fleat binding mechanism permanently attached thereto, said integral piece of. flexible material being of reduced strength along two lines substantially parallel with and at opposite sides of the back, so as to provide definite lines for the bending or hinging of the flexible covers relativelyto the back.

6. In a temporary binder, a 4one-piece vflexible member constituting the back and covers, provided with a weakened portion extending lengthwise on each side of the operating parte, said weakened portion ter minating before the edges of the covers are reached, and means to secure the back and covers to the operating parts.

7. ln a temporary binder, a base-plate, two prong-carrying plates having their outer longitudinal edges held by said base plate, the prongs being integral with said carrying' plates, a plurality of joint blocks 15 each having4 grooves along its opposite edges engagingkthe adjacent inner edges of said carrying plates, said carryin plates having notches engaging said blocks, and

an upper spring plate acting on said carrying plates to hold them yizeldingly in the positionscorresponding to the open and the closed positions of the prongs'.

8. In a temporary binder, a 'pair of prong carrying plates, means for pressing` them toward each other and joint blocks 15 between their inner edges, said joint blocks being' tightly engaged with one of said plates and loosely engaged with the other.

9. ln a temporary binder, a base plate, a pair ot prong-carrying; plates held at their outer longitudinal edges by said base plate and an upper spring plate acting on said carrying plates to hold them yieldingly in the .positions corresponding to the open and the closed positions of the rongs.
